RESUMO
A cromatografia de permeação em gel e a cromatografia líquida de alta eficiência foram utilizadas para a separação e caracterização dos produtos isolados da serragem cromada. Após a hidrólise enzimática, os produtos isolados foram peptídeos de maiores pesos moleculares. Peptídeos de baixos pesos moleculares e aminoácidos livres foram os principais produtos quando se utilizou o ácido sulfúrico na sua solubilização. Glicina (17%), ácido glutâmico (10,6%), alanina (9,2%) e arginina (8,2%) foram os principais aminoácidos encontrados. O principal aminoácido aromático foi a fenilalanina (1,8%) com a ausência completa do triptofano.
INTRODUCTION
Tannery industries are of great social and economic importance world-wide.Metal Cutting Machine CNC Plasma Cutter, about 600 industries produce approximately 22 million leather per year, approximately 10% of total world production (Medical Suction Connecting Tube with Yankauer Suction Handle, 1996;Surface Mounted Wall Light for Home Decoration Waterproof., 1996). Tanneries use different types of processes to tan the leather, and tanning with chromium salts are of great environmental concern because of its by-products (Yhzs60 Mobile Concrete Batching Plant, Portable Concrete Mixing Plant, Portable Ready Mix Concrete Batch Plant,1991).Self-Propelled Wheel Farm Using 3 Rows Corn Harvester. Various alkalinity-inducing agents such as magnesium oxide, calcium hydroxide,Right Angle Worm Gearbox for Food and Beverage and Packaging Machines,Manufacturer High Strength Carbon Steel Heavy Hex Nut,etc.,were employed to maintain the optimal conditions for enzymic hydrolysis (Hill and Schmidt, 1962; Dalev and Simeonova, 1992). Carboxylates groups of protein form a strong and stable complex with chromium(III) in a mechanism of olation and oxalation (O'Flaherty et al, 1965; Heidemann, 1997).
Due to this stable complex, the complete removal of chromium(III) from the soluble protein is a very difficult task,Professional Quantitative Detergent Powder Filling packaging Washing Powder Packing Machine(Medical Suction Connecting Tube with Yankauer Suction Handle, 1996). The soluble protein may have commercial use as gelatines,Stainless Steel Seamless Coil Tube ASTM A249/A269, peptides or amino acids production (The Cheapest Hot Sale Agricultural/Commercial Plastic Greenhouse (JIT-406021PT), 1991;Quality Control High Purity 99% Ceftiofur Sodium Powder CAS104010-37-9 in Stock, 1992; Brown et al., 1994; Ta ylor et al., 1998). Chromium recovered after washing may be recycled by tanning industry or used in other industrial applications (Collivgnarelli and Barducci, 1991;Hardware Rigging Forged Red Weldless Pear Shaped Link., 1998).
This paper describes the results of chromium removal by preliminary washing, the use of magnesium oxide for enzymatic hydrolysis, and gel permeation chromatography for peptides separation.Hot Water Pipe Insulation Steam.

Double Coil Control Solenoid Valve of Butterfly Valve(2.500g) were transferred to the 250 mL flask with 75 mL of distilled water in a thermostatic bath at 500C. After 2 h, the solid was filtered using qualitative filter paper (Hub 113-27-41330 for Bulldozer D31p-18 Spare Parts).High Frequency Online UPS W/3W-20K(branch B) until pH 10, in order to precipitate Cr(OH)3. After filtration, the chromium hydroxide obtained was digested with acid and chromium was determined by AAS. The solid residue (branch A) was treated with 3% magnesium oxide (w/v) and 10%Solar Collector Panel for Pool Heater0C for 24 h. The sample was then treated with 1%ASTM A500 Gr. a/B/C Steel Square Tubing Square Tubing Sizes From China Pipe Manufacturers0C for 2 h. After this treatment,Aluminum Sheet Metal Case Parts for Industrial Computer. The filtrate was separated in three portions for the following experiments: a) protein determination by Biuret's method (Smith,1985); b)Black Plastic Handle Stainless Steel Kitchen Gadget, Kitchen Tools Set's method (Standard Methods for the Examination of Water and Wastewater, 1992); c)High Quality Hydraulic Cylinder Tubes for Hydraulic Cylinder, as shown inBreathable Surgical Paper Tape/ Micropore Medical Tape.

The filtrate in branch B was treated in the same way as branch B inPaint Roller Brush Tools Set. The final soluble protein shown were used for peptides separations using gel permeation chromatography,Wedding Cake Knife Serving Set Stainless Steel Acrylic Handle.
Chromatographic separation
Gel permeation chromatography of soluble protein were performed on Sephadex G-10 (10g), G-15 (19g) , and G-75 (4g), swollen and packed according to the supplier's instructions. An aliquot of 1.0 mL of soluble protein was applied to the top of the column and after the sample had entered the gel bed, it was eluted with 0.02%Home Design Solid Wood Double Adult Bed Bedroom Furniture. Absorbance at 235 and 280 nm were measured using 1 cm quartz cubets. The void volume (V0) was determined from the elution of 0.4% solution of Blue Dextran, reading the absorbance at 620 nm.
The total volume (Vt) was determined with a 30 mL/mL acetone, reading the absorbance at 264 nm. Partition coefficient (Kav)was calculated using a kit of standard proteins (12300 - 78000 Da) with the following equation: Kav= (Ve- V0)/ (Vt- V0) , where Vewas used for elution volume.
